混流泵是介于离心泵和轴流泵之间的泵型需要把压水室规划成径导游叶(正导叶)加上类球形泵壳的构造型式是叶轮内安稳的相对运动的条件。为此,请求在导叶中的螺旋线有些的液体,不受任何外力的效果。
一.概述
1.用途:HW混流泵为卧式,单级,单吸,涡壳式混流泵。适用于输送清水或物理,化学性质类似于水的其它液体。被输送液体温度不宜高于50度。广泛用于农田灌溉,工业和城市排水等多种场合。HW泵的性能范围:流量90-9000m3/h 扬程3.5-22m。
2. 特点:结构简单,使用可靠,装修方便,而且效率高,体型小,重量轻。jdhuiquan6.22
3. 传动方式:用直接传动和变速传动。常用动力机是电动机和柴油机。订货 时应明确动力机的型号,以便确定联轴器和皮带轮的型号
4.型号说明:以150HW-8S例
150---------泵进出口直径mm
8------------设计扬程 m
S------------变型代号

5如果您遇到其他混流泵产品使用问题不能解决,不管是否是购买的我们的产品,都欢迎你来电咨询,以便我们把混流泵做的更好。混流泵的安装原则及注意点:1,安装原则:(1),水泵的安装高度:上水位不应高于轴承下端,下水位取决于泵的允许吸上真空度(应减去管路损失)。(2),水泵应尽可能靠近水源,以缩短进水管路,减少管路损失。(3),管路应尽量直和短。一般在进水口用一只90°或33°弯管,水泵底脚基础斜浇,可省去出水弯管。注意事项:(1),用皮带传动时,水泵和动力机的皮带轮应对正。皮带轮和皮带外要设安全罩。(2),泵盖一般不宜直接连弯管,应先接直管后再接弯管,以保证进口处流速分布均匀。(3),管路各连接法兰间。
二.结构和作用
1.HW pump mainly has pump cover, impeller, pump body, pump shaft, bushing, and bearing body and other major components. The pump cover is connected with the pump body and the inlet pipe respectively. 2. There should be an appropriate gap between the pump cover plane and the impeller plane. The gap is too small will produce friction, the gap is too large, will lead to the pump body pressure water a large number of reflux, is the pump efficiency reduction. The suitable gap used in practice is 0.3-0.7mm, and the gap can be adjusted by adding and subtracting the thickness of the paper pad.

这种泵结构简单,便于移动,适用于农田排灌,故称它为混流式农排泵。农用水泵的安装技术要求很严格。首先,水泵底座要牢固,并尽量缩短吸水管的长度。其次。2.导叶式混流泵有的又叫斜流泵。导叶式混流泵与蜗壳式不同之处进水管路应密封可靠。底阀与胶管用绳索系牢。水源为渠道的,底阀应高于水底0.5米以上,且加网防止杂物进入泵内。第三是在机泵皮带传动时,皮带的紧边应在下,以提高传动效率。水泵叶轮转向应与箭头方向保持一致。检查水泵应注意三点:(1)泵轴应能灵活转动,无撞击声;泵轴径向无明显晃动,需加足润滑油。(2)检查进水胶管有无破损,如有开裂要及时粘修。检查各紧固螺栓有无松动,要拧紧松动的螺栓。(3)潜水泵的电机绕组。
3. The shaft is applied to protect the pump shaft and should be replaced in time after wear.
1. Screw holes at the upper end of the pump body, used for filling water diversion or connecting vacuum pump pumping gas to divert water.
2. In order to expand the scope of application of the pump to meet the different needs of users, can cut the outer diameter of the impeller or exchange different perbance of the impeller.
